Alessio Quaglino 4bb6aeb19f Change site and frame attach API. 
Old API:
```
site.attach(child_spec)
frame.attach(child_spec)
```

New API:
```
parent_spec.attach(child_spec, frame=frame_name_or_object)
parent_spec.attach(site_spec, site=site_name_or_object)
```

This enables accessing the parent object during attach, which will be used in a follow-up CL to automatically append the child assets to the parent.
